I used to be VERY into baseball cards. When I was about 7-10, I'd spend every penny I had on them. Mostly 86-89 years, almost all Topps. So now, ~20 years later, I am picking them up from my folks house this week.
Several complete sets, many in binders, some in hard plastic holders... we're talking 10's of thousands probably. All but a couple are mint.
Anyone buy or sell these years cards recently? Better to sell off individually, in groups, or all at once? Took a quick look on ebay, didn't see any collections similar to this one to judge a price.
Ideas?
